LANDEN 36N 5 Gallon Rimless Low Iron Nano Aquarium Tank Review (2026)

Who the 36N is built for

The LANDEN 36N is aimed at aquascapers who want a display quality nano tank rather than a beginner all in one kit, since it ships as a bare glass shell with an included leveling mat and nothing else. Its 5 gallon size, measuring 14.2 inches wide by 8.7 inches deep by 10.2 inches tall, sits in a sweet spot that is roomier and more forgiving on water parameters than a 1 to 3 gallon nano, while still being compact enough for a desk or shelf. It tops the site's ranking of nano aquariums, reflecting how well suited it is to shrimp colonies, moss based layouts and small nature style scapes where clean glass and a rimless view matter more than built in features.

The glass and build explained

LANDEN uses low iron, ultra white glass rated at over 91 percent light transmittance, which is what gives rimless nano tanks their clearer, less green tinted look compared with standard green tinted glass. The panels are 5mm thick and the maker describes the edges as hand finished, mirror polished and chamfered, details that matter on a rimless tank since there is no plastic trim to hide a rough edge. Silicone seams are applied in thin, even lines, which keeps the seams from becoming a visual distraction on a tank meant to be photographed. Empty, the tank weighs a bit over 10 pounds, light enough to move without help but still solid glass rather than acrylic, which will not scratch as easily during aquascaping work.

Setting it up and living with a bare shell

Because the 36N is sold as a bare tank, plan on sourcing a filter, light, heater if needed, and either an aqua soil or inert substrate before it is ready to stock. The included leveling mat should always go under the tank on the stand, since rimless glass has no frame to distribute pressure and an uneven surface can stress the panels over time. LANDEN markets this size for dwarf shrimp colonies, mosses and small nano fish, which lines up with how most aquascapers actually use it, layered with aqua soil and hardscape rather than run as a plain community tank. Because there is no rim, top mounted equipment needs nano sized clips designed for thin glass edges.

How it compares with other nano tanks

Against the Ultum Nature Systems UNS 5N, which carries the same score on the site's ranking, the LANDEN 36N is a close peer in both size and build quality, with the choice often coming down to which brand's accessory ecosystem, such as matching lights and lids, an aquascaper already prefers. Against smaller 3 gallon rimless options like the LAQUAL or JBJ Picotope, the 36N's larger 5 gallon volume gives more buffer against temperature swings and water parameter shifts, at the cost of a bit more counter or desk space. It clearly outranks budget all in one nano kits with a built in filter and light, since those trade rimless glass quality and photographic clarity for convenience.

Verdict and who should choose differently

For an aquascaper who wants a clean, photograph ready nano tank and does not mind sourcing the rest of the equipment separately, the LANDEN 36N is a strong choice backed by genuinely premium low iron glass. Buyers who want a single box solution with a filter and light already included, or who are on a tight budget and do not need low iron clarity, will get more value from a framed or all in one nano kit instead. Anyone planning a true micro nano under a gallon or two should also look further down this ranking, since the 36N's 5 gallon size is built for a slightly larger footprint than that.
